3RT, 3RH, 3TB, 3TC, 3TH, 3TK Contactors for Special Applications
3TK20 Contactors
4-pole, 4 kW
■ Overview
■ Application
AC and DC operation
IEC 60947 (VDE 0660).
The contactors are suitable for use in any climate.
The main area of application for the 3TK2 contactors with flat
connectors is in household equipment. These contactors are
also suitable for simple electric controllers. No auxiliary switch
blocks can be retrofitted.
The contactors with screw terminals are finger-safe
according to EN 50274.
The contactors are available in versions with screw terminals,
6.3 mm plug connectors and solder pin connectors for soldering
in printed circuit boards.
